When entered directory into the command line, this:
当在命令行中输入目录时，这个：
ls -d -1 "/Volumes/Development/My Project/Project"/**/* | grep \.png$
Prints a list of all the file ending in .png.
打印所有以.png.
However when I try and create a script:
但是，当我尝试创建脚本时：
#! /bin/bash

# Tempoary dir for processing
mkdir /tmp/ScriptOutput/ ;
wdir="/Volumes/Development/My Project/Project" ;
echo "Working Dir: $wdir" ;
# Get every .PNG file in the project
for image in `ls -d -1 "$wdir"/**/* | grep \.png$`; do
...
done
I get the error:
我收到错误：
cp: /Volumes/Development/My: No such file or directory
The spaceis causing an issue, but I don't know why?

Another option is to change IFS:
另一种选择是更改 IFS：
OLDIFS="$IFS" # save it
IFS="" # don't split on any white space
for file in `ls -R . | grep png`
do
echo "$file"
done
IFS=$OLDIFS # restore IFS
Read more about IFS in man bash.
在 中阅读有关 IFS 的更多信息man bash。

you can try, [[:space:]] in place of space
你可以试试用 [[:space:]] 代替空格
wdir="/Volumes/Development/My[[:space:]]Project/Project"
or execute command to convert single space
或执行命令转换单个空格
wdir=`echo "$wdir" | sed 's/[[:space:]]/\[[:space:]]/g'`

If you fine with using while readand subprocess created by pipe, you can:
如果您可以使用while read管道创建的子进程，则可以：
find . -name '*.png' | while read FILE
do
echo "the File is [$FILE]"
done
